Abstract
Retraction of ‘New synthesis of 2-aroylbenzothiazoles via metal-free domino transformations of anilines, acetophenones, and elemental sulfur’ by Tien V. Huynh et al., RSC Adv., 2020, 10, 18423–18433, https://doi.org/10.1039/D0RA01750G.
Tien V. Huynh, Ngoc T. K. Luong, Duyen T. P. Nguyen, Tung T. Nguyen and Nam T. S. Phan hereby wholly retract this RSC Advances article due to irreproducibility of the reaction yields.
Khang V. Doan and Son H. Doan were informed about the retraction of the article, but have not responded to any correspondence regarding the retraction.
The results shown in Table 2 (the synthesis of compounds 3aa–3df) could not be reproduced when freshly opened reagents and solvents were used. It could be reasoned that the reported reagents were contaminated with unknown impurities, which have facilitated the reaction.
The corresponding authors regret this carelessness and apologise for any inconvenience to readers.
Signed: Tien V. Huynh, Khang V. Doan, Ngoc T. K. Luong, Duyen T. P. Nguyen, Son H. Doan, Tung T. Nguyen and Nam T. S. Phan.
